How can I connect slider and angle in the GUI?

Hello, I want to make the GUI change the angle when using the slider.

for example, in this photo, the first slider moves the first angle from 0 to 2pi.

I think I need to connect the angle of the slider and the shape when I click the run button on the right, but I don't know how.

Can you please attach your .m file and .fig file (using the paperclip button)?
